Title: What is the effect of concentration of acid on the rate of diffusion in agar blocks? Aim: To investigate how the concentration affects the rate of diffusion of hydrochloric acid through agar blocks Research Question: To determine how will different concentrations (0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M) of hydrochloric acid affect the rate of diffusion of sodium chloride through agar blocks? Introduction-include prediction; information you have researched before Diffusion refers to the passive movement

HOFLING HOSPITAL EXPERIMENT Hofling 1966 He wanted to see if nurses would follow orders given by an authority figure (Doctor) when the orders are given over the phone and would be breaking regulations. To study obedience in a real life setting. -The experiment involved public and private hospital wards. In Hospital ONE; 21 student nurses and 12 graduate nurses were asked to complete a questionnaire asking them what they would do if confronted by the experimental situation. This was to be the control

turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a certain concentration of road salt will have an affect on a specific type of plant. Also to see what changes will occur like the color

Red Cabbage Indicator Aim – To create a pH indicator out of a red cabbage solution and to construct a basic pH scale to determine the pH of unknown solutions. Materials - • red cabbage leaves • 250 mL beaker • hotplate or Bunsen burner‚ tripod‚ gauze mat and bench mat • 10 test-tubes – equal size • test-tube rack Methods - Part A: Making the indicator 1. Tear up one or two red cabbage leaves‚ and place them in the beaker with enough water so that the cabbage is just covered. 2. Heat the beaker

Measuring Cup Water Timer Tongs Observation/Question: Do all paper towels have the same absorbency? Are more expensive paper towels more absorbent? Hypothesis: I think more expensive paper towels are more absorbent than less expensive paper towels. Experiment: Controls: Same amount of water for each paper towel; same size paper towel used; the same surface used in each attempt; process to determine the amount of water left; the water will be left on the paper towel for the same amount of time; test

Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima beans. Background Information: In plant growth‚ calcium effects the metabolic process of other nutrient uptake that is vital for growth of the plant. Calcium also strengthens the cell wall structure (It is an essential part of the cell wall);

Method: The placebo controlled experiment design can be helpful in this study. In order to determine the effect of caffeinated energy drink‚ the total of twenty athletes will volunteer to participate in it. All the participants will be divided into two groups; ten will drink caffeinated energy drink and other ten will ingest placebo (no caffeine content). The drinks will be served in an opaque bottle to avoid its identification and to make sure that player drink beverages in it entirely. Both the
